Where to buy Free and Clear laundry detergent?

My wife and I are going to Japan soon. First time. We're packing extremely light, so we expect to do laundry several times. I read a post in this sub a couple of weeks ago that someone got an awful rash, and they suspect it was from the laundry detergent. My wife and I have pretty sensitive skin, so this concerned me. In the US many laundry detergent brands have a "Free and Clear" version that has less harsh dyes and scents, made for people with sensitive skin. Is there an equivalent that we can buy in Japan? If so, where? (We'll be mainly in Tokyo and Kyoto).

Thanks!
